Running the Pushover Analysis
From the Model tab The Pushover Analysis can be run via the Calculation Sequence dialog by enabling the Pushover Calculation, as shown in below. By default, both the RC calculation and Steel calculation will also be enabled.
Launch Pushover Calculation – Model tab
From the Analysis tab, the Pushover Analysis can be run by using Pushover Calculation available on the ribbon under Launch Calculation, as shown below.
Launch Pushover Calculation – Analysis tab
Depending on the material and the type of Plastic Hinges, certain results need to be available, to be calculated. Thus, in some cases, it is mandatory to perform the RC calculation or the Steel calculation.
Requirements for the calculation of the Plastic Hinges on steel elements
- If the Definition is set to Auto Defined and the Cross-section class is set to auto class – the Steel calculation needs to be run (cross-section class is required for the computation of the plastic hinge).
User Defined plastic hinge + auto cross section class
- If the Definition is set to Auto Defined and the Cross-section class is imposed – the Steel calculation is not necessary.
- If the Definition is set to User Defined and the Yield Bending Moment and Yield Rotation are imposed, as shown below, the Steel calculation is not necessary, even if the Cross- section class is set to auto class.
User Defined plastic hinge + auto cross section class
- If the Definition is set to User Defined and the Yield Bending Moment and Yield Rotation are set to be computed by the software – the Steel calculation needs to be run.
- If the Definition is set to Auto Defined and the Plastic Hinge is defined along the X direction – the Steel calculation needs to be run (𝑁𝑐𝑟 is required for the computation of the plastic hinge).
- If the Plastic Hinge is defined along the X direction and the Yield Axial Force is custom defined – the Steel calculation is not necessary.
Auto defined - DOF on local X enabled
Currently, on Advance Design only I-shaped cross-sections (W, IPE, HEA, etc.) can be used for the Auto defined Plastic Hinges.
Requirements for the calculation of the Plastic Hinges on reinforced concrete elements
- If the Definition is set to Auto Defined, the RC calculation needs to be run with the Detailed rebar definition on beams and columns enabled from the Calculation Settings. The real reinforcement is required for the computation of the Yield Bending Moments, Yield Rotations and the Limit states/Acceptance criteria.
Reinforced concrete – Calculation settings
- If the Definition is set to User Defined, and the plastic hinge properties are imposed, the RC calculation is not necessary.
Currently, on Advance Design only square, rectangular, circular, and Tee cross-sections can be used for the Auto defined Plastic Hinges.
